摘要
通过分析现实场景下设备的移动轨迹,发现其链路持续时间互补累积分布具有幂律特征;熟悉度-频繁度分布具有节点比例差异和时间无关性特征。从社会学的角度,说明这两种分布特征符合节点移动和节点间组织关系的社会性。实验证明这两种分布可以作为衡量节点社会性的重要参数,对社会网络环境下自组网的仿真研究和实际应用具有指导意义。
Analyzing the movement traces from real scenarios, we demonstrate that the complementary cumulative distribution function of contact duration, which follows an approximation power law, familiarity-regularity distribution is consistent with the characteristics of the relationships in real scenarios. Furthermore, from the view point of sociology, the reasons that causes the characteristics of these two distributions are analyzed. The results show that these two distributions can be used to measure the sociality of real traces effectively. It can provide guidance for the simulation of applications and systems designed for human-like mobile environments in MANET.
